Compatibility Notes

c-treeACE offers significant new features and enhancements. With these new additions come a few points to be aware of when moving from a previous version of c-tree Plus. FairCom strives to maintain backward compatibility whenever possible with existing applications, and c-treeACE V9.0 is no exception: all current data and index files remain completely compatible with no changes. The biggest change is a new directory layout reflecting the ease of use philosophy of the new c-treeACE product. Other changes affect transaction log formats, Unix permissions, and some c-treeACE SQL system table changes. These are all described in the following sections and should be relatively easy to navigate as you upgrade.
